Waste water treating apparatus

Abstract

The present invention relates to a wastewater treatment apparatus capable of efficiently removing oil and foreign substances in wastewater in a manner in which wastewater in a treatment tank is discharged to the outside while passing through a plurality of filter members by negative pressure of vacuum. The wastewater treatment apparatus comprises: a housing forming a filtering space and having aninlet and an outlet; a plurality of filter members installed in the filtering space to separate and remove foreign substances contained in the wastewater; a plurality of bypass spaces partitioned on both sides of the filtering space and bypassing the wastewater to another filter member located next when one of the filter members is blocked; and a vacuum pump connected to the outlet of the housingand generating a vacuum negative pressure which is negative pressure.

Description

technical field [0001] The present invention relates to a wastewater treatment device that separates and removes grease and foreign matter contained in wastewater, and relates to a device capable of discharging wastewater in a treatment tank to the outside while passing through a plurality of filter members by means of vacuum negative pressure as a negative pressure A wastewater treatment device that efficiently removes grease and foreign substances in wastewater. Background technique [0002] In general, as a method of purifying and treating industrial waste water, livestock waste water, waste oil water, waste oil, etc. (hereinafter collectively referred to as "waste water"), etc., mainly used water treatment devices perform purification by storing waste water in a After treatment, a flocculant is added to coagulate foreign substances such as floating substances contained in the wastewater and settle down to the bottom, or a method of passing the wastewater through a screen...

AI Technical Summary

Problems solved by technology

[0003] Among these water treatment methods, the latter method filters and removes foreign matter contained in waste water by passing the waste water through a screen device. During the passage through the screen device, it is difficult to expect the effect of completely filtering the foreign matter, and there are Due to the disadvantage that waste water cannot be purified only with screen devices, there is a problem that secondary water treatment devices need to be operated in parallel in order to purify and treat waste water more reliably, requiring large-scale water treatment equipment

[0004] However, it is actually difficult for small-scale small and medium-sized enterprises or micro-enterprises to install large-scale water treatment equipment. In particular, all water treatment equipment so far has the problem of not being able to more perfectly remove grease and foreign substances in terms of purification and treatment of wastewater.
